Converting a hard top to station wagon

Hi, I'm looking at converting my hard top to 6 seater spec station wagon. Assuming standard seats, fixings etc are used is there anything significant to be aware of from an insurance perspective as I believe this is a common change to make. Will it be possible to insure or is it a case that the vehicle was not originally fitted with 6 seats so you cannot insure it that way? Sorry if its a basic question but I don't want to go down the line of spending the time and money doing a proper job only to come up with an issue when I'm being honest with the insurer.

We'll still insure it as a commercial but with additional seating. Will you be fitting additional windows to it?

If you need a quote, feel free to PM me your details and we'll give you a call.

Regards,
Jordan
